Irritating to e. Carcigenicity Description IARC NTP OSHA ACGIH 3. COMPOSITION/INFORMATION ON INGREDIENTS Information on hazardous ingredients Chemical description Dibenzoyl peroxide, paste, 50% in silicone oil Composition / information on ingredients Applicable Number % w/w CAS-number Chemical name Polydimethylsiloxanes Dibenzoyl peroxide Water Page 1-9

2 This material is classified as hazardous under OSHA regulations. 4. FIRST AID MEASURES Most important symptoms and effects Irritating to e. May cause sensitization by skin contact. Description of first aid measures General In all cases of doubt, or when symptoms persist, seek medical attention. Inhalation Remove to fresh air. If t breathing, give artificial respiration. Oxygen may additionally be given, by trained personnel, if it is available. Get medical attention if symptoms occur. Skin Immediately wash skin with soap and plenty of water. Remove contaminated clothing and shoes. Get medical attention if symptoms occur. Wash clothing before reuse. Thoroughly clean or destroy contaminated shoes. Eye Immediately flush e with plenty of water. If easy to do, contact lenses should be removed during the flushing, by trained personnel. Hold the eyelids apart during the flushing to ensure rinsing the entire surface of the eye and lids with water. Get medical attention if irritation persists. Ingestion Call a physician or a poison control center immediately. Induce vomiting only if directed by medical personnel. The patient should lie on their left side while vomiting to reduce the risk of aspiration. Never give anything by mouth to an unconscious or convulsing person. Indication of any immediate medical attention and special treatment needed Persons with pre-existing skin, eye, or respiratory disease may be at increased risk from the irritant or allergic properties of this material. Attending physician should treat exposed patients symptomatically. 5. FIRE-FIGHTING MEASURES Extinguishing media waterspray, foam, sand, dry chemical powder, CO2. Unsuitable extinguishing media halons. Hazardous decomposition / combustion products CO2, Carbon moxide. Benzoic acid, Benzene. Protective equipment Firefighters must wear fire resistant protective equipment. Wear approved respirator and protective gloves. Evacuate all n-essential personnel. Extinguish a small fire with powder or carbon dioxide then apply water to prevent re-ignition. Cool closed containers with water. Water used to extinguish a fire should t be allowed to enter the drainage system or water courses. After a fire, ventilate thoroughly the area and soak with water, clean the walls and metallic surfaces. Fire and explosion hazard CAUTION: reignition may occur. Decomposition under effect of heating (See also Section Hazardous decomposition products). If involved in a fire, it will support combustion. In case of fire and/or explosion do t breathe fumes.

Environmental precautions Do t allow to enter drains or water courses. Methods and material for containment and cleaning up Stop leakage if possible. Eliminate all sources of ignition, and do t generate flames or sparks. Transfer remaining product from leaking container to a clean and suitable container. Cover the remainder with inert absorbent (e.g. vermiculite) for disposal. Keep contents moist. The waste should NOT be confined. Flush surroundings with large amounts of water and soap. CAUTION: reignition may occur. Evacuate personnel to safe area. 7. HANDLING AND STORAGE Precautions for safe handling Never weigh out in the storage room. When using do t eat, drink or smoke. Do t breathe fumes/vapor. Handle in well ventilated areas. Eliminate all sources of ignition, and do t generate flames or sparks. Keep away from reducing agents (e.g. amines), acids, alkalies and heavy metal compounds (e.g. accelerators, driers, metal soaps). Keep product and emptied container away from heat and sources of ignition. Confinement must be avoided. Do t allow to dry out. Avoid contact with skin and e. Avoid Incompatible materials (See Section 10). Fire and explosion prevention Do t cut or weld on or near this container even when empty. Conditions for safe storage Store in accordance with local/national regulations. Keep away from food, drink and animal feedingstuffs. Store in a dry well ventilated place away from sources of heat and direct sunlight. Store separate from other chemicals. Keep only in the original container. Keep container upright to prevent leakage. Storage For maximum quality store below: 30 C. It is recommended to use electrical equipment of temperature group T3. However, autoignition can never be excluded. Wash hands thoroughly after handling or contact. Keep work clothes separate and do t take them home. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Control parameters Ensure good ventilation and local exhaustion of the working area. Explosion proof ventilation recommended. Personal protection Respiratory Provide adequate ventilation. In case of insufficient ventilation wear suitable respiratory equipment (respirator with Filter P1). Hand Wear suitable protective gloves of neoprene or synthetic rubber. Skin and body Wear suitable protective clothing. Emergency-shower and facilities for rinsing e must be accessible. Launder clothes before reuse. Dibenzoyl peroxide Page 3-9

STABILITY AND REACTIVITY Chemical stability SADT - (Self accelerating decomposition temperature) is the lowest temperature at which self accelerating decomposition may occur with a substance in the packaging as used in transport. A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can be caused by thermal decomposition at and above the following temperature: 70 C. Contact with incompatible substances can cause decomposition at or below the SADT 70 C. Conditions to avoid To maintain quality store in original closed container below: 30 C. Avoid shock and friction. A high degree of confinement must be avoided. Incompatible materials Avoid contact with rust, iron and Copper. Contact with incompatible materials such as acids, alkalies, heavy metals and reducing agents will result in hazardous decomposition. Do t mix with peroxide accelerators. Use only Stainless steel 316, PP, polyethylene or glass-lined equipment. Contact Akzo Nobel for more information. Possibility of hazardous reactions Polymerization does t occur. Hazardous decomposition products Hazardous decomposition products; Benzoic acid, Benzene. Emergency procedures will vary depending on conditions. The customer must have an emergency response plan in place. Contact Akzo Nobel for assistance with developing an emergency response plan. 11.
